"WebbYou shouldn't be getting the standard deviation or the mean from a Z-table. The Z-table assumes a mean of 0 and a standard deviation of 1 (hence why we calculate a z-score before going to the table). The table has two uses: 1. Calculate a z-score and find the probability under the curve. 2. Look up a probability and find the z-quantile. " - Proportion of scores calculator
